7. Remove and discard discharge grille by

removing attachment screws from inside of

front panel. See Fig 6.

8. Optional – for easy access to control panel,

remove the control door by removing the hinges

pins from inside of front panel that secure

control door in place.

9. Replace the front panel.

Install Extension Duct

(Use for Left or Right Applications)

10. Temporarily secure plenum to support brackets

previously installed.

11. Establish the position where the extension

should intersect the adjacent wall and mark this

location.

12. Measure and cut a 3

3/4 in. x 7 1/8 in. opening

through the wall. See Fig. 7.

13. The Extension Duct Wall Trim Kit can be used

to trim out, up to approximately a 1/2 inch gap

around the Extension Duct.

14. Establish the needed length of the Extension

Duct. Be sure to include the thickness of the

wall in determining the proper length. One

suggested method is to measure from the

support bracket to outer wall surface in the

adjacent room.

15. Cut the Extension Duct to length. Do not cut

flanged end as this is inserted into the plenum.

Only cut the non-flanged end of the Extension

Duct. See Fig 8.
